ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
EPAM Systems, Inc. (the “Company” or “EPAM”) is a global provider of digital engineering, cloud and AI-enabled transformation services, as well as a leading business and experience consulting partner for global enterprises and ambitious startups. EPAM leverages AI to deliver transformative solutions that accelerate its clients' digital innovation and enhance their competitive edge. In a business landscape that is constantly challenged by the pressures of digitization, EPAM focuses on building long-term partnerships with clients in various industries through innovative and scalable software solutions, integrated strategy, experience and technology consulting, and a continually evolving mix of advanced capabilities. The Company is incorporated in Delaware with headquarters in Newtown, Pennsylvania.
Basis of Presentation — The accompanying unaudited condensed consolidated financial statements of EPAM have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP” or “U.S. GAAP”) and Article 10 of Regulation S-X under the Securities Exchange Act of 1934, as amended. The unaudited condensed consolidated financial statements include the financial statements of EPAM Systems, Inc. and its subsidiaries with all intercompany balances and transactions eliminated.
These unaudited condensed consolidated financial statements and accompanying notes should be read in conjunction with the Company’s audited consolidated financial statements and the notes thereto for the year ended December 31, 2025 included in its Annual Report on Form 10-K. The preparation of these condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in these condensed consolidated financial statements and accompanying notes. Actual results could differ from those estimates, and such differences may be material to the unaudited condensed consolidated financial statements. Operating results for the interim periods are not necessarily indicative of results that may be expected to occur for the entire year. In management’s opinion, the accompanying unaudited condensed consolidated financial statements include all normal and recurring adjustments necessary for a fair presentation of the Company’s financial position as of September 30, 2026 and the results of its operations and its cash flows for the periods presented.
Risks and Uncertainties — As a result of its global operations, the Company may be subject to certain inherent risks.
Concentration of Credit — Financial instruments that potentially subject the Company to concentration of credit risk consist primarily of cash, cash equivalents, short-term investments and trade receivables. The Company maintains cash, cash equivalents and short-term investments with financial institutions. The Company believes its credit policies reflect normal industry terms and business risk and there is no expectation of non-performance by the counterparties.
The Company has cash in several countries, including Ukraine and Belarus, where the banking sector remains subject to periodic instability; banking and other financial systems generally do not meet the banking standards of more developed markets; and bank deposits made by corporate entities are not insured. The Company regularly monitors cash held in these countries and, to the extent the cash held exceeds the amounts required to support its operations in these countries, the Company distributes the excess funds into markets with more developed banking sectors to the extent it is possible to do so. As of September 30, 2026, the Company had $28.3 million of cash and cash equivalents in banks in Ukraine and $25.1 million of cash and cash equivalents in banks in Belarus. In April 2024, Belarus instituted restrictions on distributing dividends from Belarus to shareholders in certain countries, including the U.S. The restrictions are scheduled to remain in place until the end of 2026 and may prevent EPAM from distributing excess funds, if any, out of Belarus. The Company does not expect these restrictions to have a material impact on its ability to meet its worldwide cash obligations during this period. The Company places its cash and cash equivalents with financial institutions considered stable in the region, limits the amount of credit exposure with any one financial institution and conducts ongoing evaluations of the credit worthiness of the financial institutions with which it does business. However, a banking crisis, bankruptcy or insolvency of banks that process or hold the Company’s funds, or sanctions may result in the loss of deposits or adversely affect the Company’s ability to complete banking transactions, which could adversely affect the Company’s business and financial condition.
Trade receivables are generally dispersed across many clients operating in different industries and geographies; therefore, concentration of credit risk is limited. Historically, credit losses and write-offs of trade receivables have not been material to the consolidated financial statements. If the Company’s clients enter bankruptcy protection or otherwise take steps to alleviate their financial distress, the Company’s credit losses and write-offs of trade receivables could increase, which would negatively impact its results of operations.
Foreign currency risk — The Company’s global operations are conducted predominantly in U.S. dollars. Other than U.S. dollars, the Company generates revenues in various currencies, principally in euros, British pounds, and Swiss francs and incurs expenditures principally in euros, Polish zlotys, Indian rupees, British pounds, and Mexican pesos. The Company’s international operations expose it to risk of adverse fluctuations in foreign currency exchange rates through the remeasurement of foreign currency denominated assets and liabilities (both third-party and intercompany) and translation of earnings and cash flows into U.S. dollars. The Company has a hedging program whereby it enters into a series of foreign exchange forward contracts with durations of twelve months or less that are designated as cash flow hedges of forecasted Polish zloty, Indian rupee, Hungarian forint, Colombian peso, and Mexican peso transactions. See Note 5 “Derivative Financial Instruments” for further information on the Company’s hedging program.
Interest rate risk — The Company is exposed to market risk from changes in interest rates. Exposure to interest rate risk results primarily from variable rates related to cash and cash equivalent deposits, short-term investments and the Company’s borrowings, mainly under the 2025 Credit Agreement, which is subject to a variety of rates depending on the type and timing of funds borrowed (See Note 6 “Debt”). The Company does not believe it is exposed to material direct risks associated with changes in interest rates related to these deposits, investments and borrowings.

The foreign exchange derivatives are valued using pricing models and discounted cash flow methodologies based on observable foreign exchange data at the measurement date. See Note 5 “Derivative Financial Instruments” for additional information regarding derivative financial instruments.
The fair value of the contingent consideration liabilities was determined using a probability-weighted expected return method and is based on the expected future payments to be made to the sellers of the acquired businesses in accordance with the provisions outlined in the respective purchase agreements. Although there is significant judgment involved, the Company believes its estimates and assumptions are reasonable. In determining fair value, the Company considered a variety of factors, including future performance of the acquired businesses using financial projections developed by the Company and market risk assumptions that were derived for revenue growth and earnings before interest and taxes. The Company estimated future payments using the earnout formula and performance targets specified in the purchase agreements and adjusted those estimates to reflect the probability of their achievement. Those weighted average estimated future payments were then discounted to present value using a rate based on the weighted average cost of capital of guideline companies. The discount rates used to determine the fair value of contingent consideration for the Company’s acquisitions were between 12% and 20%.
Changes in financial projections, market risk assumptions, discount rates or probability assumptions related to achieving the various earnout criteria would result in a change in the fair value of the recorded contingent liabilities. Such changes, if any, are recorded within Interest and other income (loss), net in the Company’s condensed consolidated statements of income.
A reconciliation of the beginning and ending balances of Level 3 contingent consideration liabilities using significant unobservable inputs for the nine months ended September 30, 2026 is as follows:

Revolving Credit Facility — On October 3, 2025, the Company replaced its 2021 Credit Agreement with an amended and restated credit agreement (the “2025 Credit Agreement”) with a syndicate of lenders. The 2025 Credit Agreement provides for a revolving credit facility (the “2025 Revolving Facility”) with a borrowing capacity of $700.0 million, with the potential to increase the borrowing capacity up to $1,200.0 million if lenders agree to increase their commitments and the Company satisfies certain conditions. The 2025 Credit Agreement matures on October 3, 2030.
Borrowings under the 2025 Revolving Facility may be denominated in U.S. dollars or up to a maximum of $250.0 million equivalent in British pounds sterling, Canadian dollars, euros or Swiss francs and other currencies as may be approved by the lenders. Borrowings under the 2025 Revolving Facility bear interest at either a base rate or an alternative benchmark index for borrowings in currencies other than U.S. dollars. The base rate is equal to the highest of (a) the Overnight Bank Funding Rate, plus 0.5%, (b) the Prime Rate, or (c) the Daily Simple SOFR Rate, plus 1.0%, so long as the Daily Simple SOFR Rate is offered, ascertainable and not unlawful.

The majority of the Company’s performance-based equity-classified RSU awards are granted to its named executive officers and certain other members of senior management. These awards vest after 3 years, contingent on meeting certain financial performance targets, market conditions and continued service conditions. The financial performance targets are set by the Compensation Committee of the Board of Directors at the beginning of each year. For the portion of the awards subject to market conditions, fair value was determined using a Monte Carlo valuation model. The portion of the awards associated with financial performance in future years for which the financial performance targets have not yet been determined are not considered granted for accounting purposes.
As of September 30, 2026, the Company has issued 114 thousand performance-based equity-classified RSUs which are not considered granted for accounting purposes as the future vesting conditions have not yet been determined and these awards are not reflected in the table above.

Employee Stock Purchase Plan
The 2021 Employee Stock Purchase Plan (“ESPP”) enables eligible employees to purchase shares of EPAM’s common stock at a discount at the end of each designated offering period, which occurs every six months ending April 30th and October 31st. The purchase price is equal to 85% of the fair market value of a share of EPAM’s common stock on the first date of an offering or the date of purchase, whichever is lower. During the nine months ended September 30, 2026, the ESPP participants purchased 141 thousand shares of common stock under the ESPP. During the nine months ended September 30, 2025, the ESPP participants purchased 107 thousand shares of common stock under the ESPP.
The Company recognizes compensation expense related to share issuances pursuant to the ESPP on a straight-line basis over the six-month offering period. For the three and nine months ended September 30, 2026, the Company recognized $2.4 million and $7.0 million, respectively, of stock-based compensation expense related to the ESPP. For the three and nine months ended September 30, 2025, the Company recognized $2.5 million and $7.5 million, respectively, of stock-based compensation expense related to the ESPP. As of September 30, 2026, total unrecognized stock-based compensation cost related to the ESPP was $0.8 million, which is expected to be recognized over a period of 0.1 years.
Share Repurchases
On October 16, 2025, the Board of Directors authorized a share repurchase program (the “2025 Repurchase Program”) for up to $1,000 million of the Company’s outstanding common stock. On September 30, 2026, the Board of Directors terminated and replaced the 2025 Repurchase Program (including its remaining $293 million authorization) with a new share repurchase program for up to $1,800 million of the Company’s outstanding common stock through December 31, 2029 (the “2026 Repurchase Program”). The Company may repurchase shares of its common stock on a discretionary basis from time to time through open-market purchases, privately negotiated transactions or other means, including through the use of trading plans intended to qualify under Rule 10b5-1 under the Securities Exchange Act of 1934, as amended. The timing and total amount of stock repurchases will depend upon business, economic and market conditions, corporate and regulatory requirements, prevailing stock prices, and other considerations. The share repurchase program may be suspended or discontinued at any time, and does not obligate the Company to acquire any amount of common stock. Prior to the authorization of the 2026 Repurchase Program and the 2025 Repurchase Program, the Company repurchased common stock under the 2024 Repurchase Program and exhausted the $500 million authorized under that program as of September 30, 2025.
On March 4, 2026, the Company entered into a $300 million Accelerated Share Repurchase Agreement (the “March 2026 ASR”) with Morgan Stanley & Co. LLC (“Morgan Stanley”). The March 2026 ASR was consummated under the 2025 Repurchase Program. Under the terms of the March 2026 ASR, the Company made a payment of $300 million to Morgan Stanley on March 4, 2026 and received from Morgan Stanley an initial delivery of 1.703 million shares of its common stock, or $240 million worth based on the closing price on March 4, 2026. During the three months ended March 31, 2026, the shares in the initial delivery were retired and recorded as a reduction of retained earnings. The remaining amount was recorded as a reduction of additional paid-in capital during the first quarter. Final settlement of the March 2026 ASR occurred on April 17, 2026, when Morgan Stanley delivered 537 thousand additional shares of the Company’s common stock. These shares were valued at $70.5 million on the delivery date, which was recorded as an increase to additional paid-in capital and a corresponding reduction to retained earnings. All shares repurchased under the March 2026 ASR were immediately retired upon receipt by the Company. The final number of shares repurchased was based on the volume-weighted average price of the Company’s common stock during the term of the March 2026 ASR, less a discount pursuant to the terms and conditions of the March 2026 ASR.
During the three and nine months ended September 30, 2026, the Company repurchased a total of 707 thousand and 3.891 million shares of its common stock, respectively, and during the three and nine months ended September 30, 2025, the Company repurchased a total of 493 thousand and 2.376 million shares of its common stock, respectively. The Company spent $79.9 million and $488.9 million on share repurchases during the three and nine months ended September 30, 2026, respectively, and spent $82.1 million and $438.6 million on share repurchases during the three and nine months ended September 30, 2025, respectively. All of the repurchased shares have been retired.

Income Tax Disclosure [Abstract]  
INCOME TAXES INCOME TAXES
In determining its interim provision for income taxes, the Company uses an estimated annual effective tax rate, which is based on expected annual profit before tax, statutory tax rates and tax planning opportunities available in the various jurisdictions in which the Company operates. Certain significant or unusual items are separately recognized in the quarter in which they occur and can be a source of variability in the effective tax rates from quarter to quarter.
The Company’s worldwide effective tax rate for the three months ended September 30, 2026 and 2025 was 26.1% and 25.6%, respectively, and 27.8% and 25.8% during the nine months ended September 30, 2026 and 2025, respectively. The Company recorded tax shortfalls upon vesting or exercise of stock awards of $0.5 million and $12.1 million during the three and nine months ended September 30, 2026, respectively, compared to tax shortfalls of $0.2 million and $0.8 million during the three and nine months ended September 30, 2025, respectively.

Earnings Per Share [Abstract]  
EARNINGS PER SHARE EARNINGS PER SHARE
Basic earnings per share is computed by dividing net income available to common shareholders by the weighted-average number of shares of common stock outstanding during the period. Diluted earnings per share is computed by dividing net income available to common shareholders by the weighted-average number of shares of common stock outstanding during the period increased to include the number of additional shares of common stock that would have been outstanding if the potentially dilutive securities had been issued. Potentially dilutive securities include outstanding stock options, unvested equity-settled RSUs and the stock to be issued under the Company’s ESPP. The dilutive effect of potentially dilutive securities is reflected in diluted earnings per share by application of the treasury stock method.
The following table sets forth the computation of basic and diluted earnings per share of common stock as follows:

Commitments and Contingencies Disclosure [Abstract]  
COMMITMENTS AND CONTINGENCIES COMMITMENTS AND CONTINGENCIES
Indemnification Obligations — In the normal course of business, the Company is a party to a variety of agreements under which it may be obligated to indemnify the other party for certain matters. These obligations typically arise in contracts where the Company customarily agrees to hold the other party harmless against losses arising from a breach of representations or covenants for certain matters, infringement of third-party intellectual property rights, data privacy violations, and certain tortious conduct in the course of providing services. The duration of these indemnifications varies, and in certain cases, is indefinite.
The Company is unable to reasonably estimate the maximum potential amount of future payments under these or similar agreements due to the unique facts and circumstances of each agreement and the fact that certain indemnifications provide for no limitation to the maximum potential future payments under the indemnification. Management is not aware of any such matters that would have a material effect on the condensed consolidated financial statements of the Company.
Litigation — From time to time, the Company is involved in litigation, claims or other contingencies arising in the ordinary course of business. The Company accrues a liability when a loss is considered probable and the amount can be reasonably estimated. When a material loss contingency is reasonably possible but not probable, the Company does not record a liability but instead discloses the nature and the amount of the claim, and an estimate of the loss or range of loss, if such an estimate can be made. Legal fees are expensed as incurred. In the opinion of management, the outcome of any existing claims and legal or regulatory proceedings, if decided adversely, is not expected to have a material effect on the Company’s business, financial condition, results of operations or cash flows.
Ukraine Humanitarian Commitment — The Company has established a $100.0 million humanitarian commitment to support its employees in Ukraine and their families. As of September 30, 2026, the Company has $2.1 million remaining to be expensed related to this humanitarian commitment. See Note 2 “Impact of the Invasion of Ukraine” for more information regarding commitment to humanitarian aid for Ukraine.
Deferred Consideration — During the year ended December 31, 2022, the Company purchased software licenses for use in the regular course of business in exchange for an upfront payment and fixed, subsequent annual payments due over the next 4 years. This agreement was modified during the years ended December 31, 2023, 2024 and 2025. As of September 30, 2026, the undiscounted deferred consideration amounts owed totaled approximately $18.5 million and are expected to be paid in 2026.
Contractual Commitment — On March 31, 2023, the Company entered into a 5-year agreement for cloud services through which it committed to spending at least $75.0 million over the term of the agreement. As of September 30, 2026, $30.3 million remains to be spent under this contractual commitment. The Company has the ability to cancel the commitment whereby it would incur a cancellation penalty of 20% of the remaining contractual commitment.

SEGMENT INFORMATION

Segment Reporting [Abstract]  
SEGMENT INFORMATION SEGMENT INFORMATION
The Company determines its business segments and reports segment information in accordance with how the Company’s chief operating decision maker (“CODM”) organizes the segments to evaluate performance, allocate resources and make business decisions. The Company’s CODM is the chief executive officer. The Company manages its business primarily based on the managerial responsibility for its client base and market. As managerial responsibility for a particular client relationship generally correlates with the client’s geographic location, there is a high degree of similarity between client locations and the geographic boundaries of the Company’s reportable segments. In some cases, managerial responsibility for a particular client is assigned to a management team in another region and is usually based on the strength of the relationship between client executives and particular members of EPAM’s senior management team. In such cases, the client’s activity would be reported through the management team’s reportable segment.

Segment results are based on the segment’s revenues and operating profit, where segment operating profit is defined as segment income from operations before unallocated costs. Expenses included in segment operating profit consist principally of direct selling and delivery costs as well as an allocation of certain shared services expenses. Intersegment transactions are excluded from the segment’s revenues and operating profit on the basis that they are neither included in the measure of a segment’s profit and loss results, nor considered by the CODM during the review of segment results. Certain corporate expenses are not allocated to specific segments as these expenses are not controllable at the segment level. Such expenses include certain types of professional fees, certain taxes included in operating expenses, compensation to non-employee directors and certain other general and administrative expenses, including compensation of specific groups of non-production employees. In addition, the Company does not allocate amortization of intangible assets acquired through business combinations, goodwill and other asset impairment charges, stock-based compensation expenses, acquisition-related costs and certain other one-time charges and benefits. These unallocated amounts are combined with total segment operating profit to arrive at consolidated income from operations as reported below in the reconciliation of segment operating profit to consolidated income before provision for income taxes. Additionally, management has determined that it is not practical to allocate identifiable assets by segment since such assets are used interchangeably among the segments.
The Company’s CODM considers the operating results of each segment on a quarterly basis and uses segment operating profit predominantly to assess the performance of each segment by comparing the results of each segment with one another and to historical performance. When combined with certain other financial information, this enables the CODM to make decisions about the reporting structure, allocation of operating and capital resources, and compensation of certain employees.
Segment revenues from external clients and segment operating profit, as well as a reconciliation of segment operating profit to consolidated income before provision for income taxes is presented below:

ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)
 9 Months Ended
Sep. 30, 2026
Accounting Policies [Abstract]  
Basis of Presentation
Basis of Presentation — The accompanying unaudited condensed consolidated financial statements of EPAM have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP” or “U.S. GAAP”) and Article 10 of Regulation S-X under the Securities Exchange Act of 1934, as amended. The unaudited condensed consolidated financial statements include the financial statements of EPAM Systems, Inc. and its subsidiaries with all intercompany balances and transactions eliminated.
These unaudited condensed consolidated financial statements and accompanying notes should be read in conjunction with the Company’s audited consolidated financial statements and the notes thereto for the year ended December 31, 2025 included in its Annual Report on Form 10-K.
Consolidation
Basis of Presentation — The accompanying unaudited condensed consolidated financial statements of EPAM have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP” or “U.S. GAAP”) and Article 10 of Regulation S-X under the Securities Exchange Act of 1934, as amended. The unaudited condensed consolidated financial statements include the financial statements of EPAM Systems, Inc. and its subsidiaries with all intercompany balances and transactions eliminated.
These unaudited condensed consolidated financial statements and accompanying notes should be read in conjunction with the Company’s audited consolidated financial statements and the notes thereto for the year ended December 31, 2025 included in its Annual Report on Form 10-K.
Use of Estimates The preparation of these condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in these condensed consolidated financial statements and accompanying notes. Actual results could differ from those estimates, and such differences may be material to the unaudited condensed consolidated financial statements. Operating results for the interim periods are not necessarily indicative of results that may be expected to occur for the entire year. In management’s opinion, the accompanying unaudited condensed consolidated financial statements include all normal and recurring adjustments necessary for a fair presentation of the Company’s financial position as of September 30, 2026 and the results of its operations and its cash flows for the periods presented.
Concentration of Credit and Interest rate risk
Concentration of Credit — Financial instruments that potentially subject the Company to concentration of credit risk consist primarily of cash, cash equivalents, short-term investments and trade receivables. The Company maintains cash, cash equivalents and short-term investments with financial institutions. The Company believes its credit policies reflect normal industry terms and business risk and there is no expectation of non-performance by the counterparties.
The Company has cash in several countries, including Ukraine and Belarus, where the banking sector remains subject to periodic instability; banking and other financial systems generally do not meet the banking standards of more developed markets; and bank deposits made by corporate entities are not insured.
Trade receivables are generally dispersed across many clients operating in different industries and geographies; therefore, concentration of credit risk is limited. Historically, credit losses and write-offs of trade receivables have not been material to the consolidated financial statements. If the Company’s clients enter bankruptcy protection or otherwise take steps to alleviate their financial distress, the Company’s credit losses and write-offs of trade receivables could increase, which would negatively impact its results of operations.
Interest rate risk — The Company is exposed to market risk from changes in interest rates. Exposure to interest rate risk results primarily from variable rates related to cash and cash equivalent deposits, short-term investments and the Company’s borrowings, mainly under the 2025 Credit Agreement, which is subject to a variety of rates depending on the type and timing of funds borrowed (See Note 6 “Debt”). The Company does not believe it is exposed to material direct risks associated with changes in interest rates related to these deposits, investments and borrowings.
Foreign currency risk Foreign currency risk — The Company’s global operations are conducted predominantly in U.S. dollars. Other than U.S. dollars, the Company generates revenues in various currencies, principally in euros, British pounds, and Swiss francs and incurs expenditures principally in euros, Polish zlotys, Indian rupees, British pounds, and Mexican pesos. The Company’s international operations expose it to risk of adverse fluctuations in foreign currency exchange rates through the remeasurement of foreign currency denominated assets and liabilities (both third-party and intercompany) and translation of earnings and cash flows into U.S. dollars. The Company has a hedging program whereby it enters into a series of foreign exchange forward contracts with durations of twelve months or less that are designated as cash flow hedges of forecasted Polish zloty, Indian rupee, Hungarian forint, Colombian peso, and Mexican peso transactions.
Adoption of New Accounting Standards and Pending Accounting Standards
Adoption of New Accounting Standards
There were no recently adopted accounting standards which had a material impact on the Company’s consolidated financial statements.
Pending Accounting Standards
From time to time, new accounting pronouncements are issued by the FASB or other standards-setting bodies that the Company will adopt according to the various timetables the FASB specifies. Unless otherwise discussed below, the Company believes the impact of recently issued standards that are not yet effective will not have a material impact on its consolidated financial statements upon adoption.
During the three months ended September 30, 2026, there have been no material updates regarding pending accounting standards as reported in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025.
Fair Value of Financial Instruments
The foreign exchange derivatives are valued using pricing models and discounted cash flow methodologies based on observable foreign exchange data at the measurement date. See Note 5 “Derivative Financial Instruments” for additional information regarding derivative financial instruments.
The fair value of the contingent consideration liabilities was determined using a probability-weighted expected return method and is based on the expected future payments to be made to the sellers of the acquired businesses in accordance with the provisions outlined in the respective purchase agreements. Although there is significant judgment involved, the Company believes its estimates and assumptions are reasonable. In determining fair value, the Company considered a variety of factors, including future performance of the acquired businesses using financial projections developed by the Company and market risk assumptions that were derived for revenue growth and earnings before interest and taxes. The Company estimated future payments using the earnout formula and performance targets specified in the purchase agreements and adjusted those estimates to reflect the probability of their achievement. Those weighted average estimated future payments were then discounted to present value using a rate based on the weighted average cost of capital of guideline companies. The discount rates used to determine the fair value of contingent consideration for the Company’s acquisitions were between 12% and 20%.
Changes in financial projections, market risk assumptions, discount rates or probability assumptions related to achieving the various earnout criteria would result in a change in the fair value of the recorded contingent liabilities. Such changes, if any, are recorded within Interest and other income (loss), net in the Company’s condensed consolidated statements of income.
Non-Marketable Securities Without Readily Determinable Fair Values
Non-Marketable Securities Without Readily Determinable Fair Values
The Company holds investments in equity securities that do not have readily determinable fair values. These investments are recorded at cost and are remeasured to fair value based on certain observable price changes or impairment events as they occur.
